摘要
利用变温核磁技术研究了杂多酸同芳磺酸的作用,提出了杂多酸催化芳烃磺化成砜的作用机理。
In this article, the interaction between HPA catalyst and arenesulfonic acid is studied by means of variable-temperature 1H NMR. The mechanism of HPA catalyzing the reactions for sulfonating aromatic compounds to aryl sulphone is proposed. The proton from HPA plays a main role in these reactions and HPAN has influence over the reaction rate and selectivity.
